## Description

SOLE Semantic Search replaces the default WordPress keyword search with semantic
search powered by SOLE Engine. Instead of matching exact words, it understands the
meaning behind search queries and returns the most relevant results.

**Features:**

 * Seamless replacement of native WordPress search
 * Configurable results per page (1-50)
 * Automatic fallback to native search if SOLE Engine is unavailable
 * Auto-translation of plugin UI when site language is non-English

**Requirements:**

 * [SOLE Engine](https://wordpress.org/plugins/sole-engine/) plugin must be installed
   and active
 * Semantic search must be enabled in SOLE Engine settings

#### External services

This plugin does not contact any external service directly. It performs its
 searches
through the required SOLE Engine plugin, which sends data to the SOLE Engine service
operated by Sole Computer (https://sole.computer) at engine.sole.computer.

SOLE Engine requires a Sole Computer account and Engine User Key. If the key
 is
missing, this plugin makes no Engine request and native WordPress search remains
in use. If SOLE Engine rejects the key, native search remains in use; an administrator
must reconnect or replace the key in SOLE Engine settings.

**What reaches the service because of this plugin.** When a visitor runs a
 search,
the search query is sent so that it can be matched semantically against your indexed
content. Your posts and pages reach the service as indexed content through SOLE 
Engine itself, not through this plugin.

**When.** On a visitor search, and when this plugin’s own interface strings are

auto-translated on a non-English site. Installing or activating this plugin sends
nothing.

Because all traffic goes through SOLE Engine, its own disclosure — including
 the
background jobs it schedules — applies here too. See the SOLE Engine plugin page
for the full description.

### Source code

The maintained source is available at https://github.com/solecomputer/sole-semantic-
search. The score stylesheet is directly maintained readable source; no bundler 
or minifier is used. Release packages are generated by a deterministic allowlisted
packaging step that normalizes line endings and removes non-distributed comments.

## Installation

 1. Install and activate the [SOLE Engine](https://wordpress.org/plugins/sole-engine/)
    plugin.
 2. Enable semantic search in SOLE Engine settings.
 3. Install and activate SOLE Semantic Search.
 4. Visit Settings > SOLE Semantic Search to configure options.

## FAQ

### What happens if SOLE Engine is not installed?

The plugin will display an admin notice asking you to install SOLE Engine. Native
WordPress search continues to work normally.

### What happens if the semantic search fails?

The plugin silently falls back to native WordPress search. No error is shown to 
visitors.

### Does this work with custom post types?

The plugin intercepts the main search query. Results depend on what SOLE Engine 
has indexed.
